- Executive summary:
A study was conducted according to Regulation (EC) No 92/69 method A.15 and DIN 51794 to determine the auto-ignition temperature of the test substance. The main test was started at the lowest auto-ignition temperature found in the preliminary test and the temperature was then decreased in intervals of 1 - 2 K. This was repeated until no ignition was observed. The auto-ignition temperature of the test item was found to be 295 °C. This value was the lowest auto-ignition temperature of three independent measurements rounded down to the nearest multiple of 5 °C.
Reference
An approximate value of the ignition temperature of the test item was first determined by a preliminary test. Table 1 gives the result of the preliminary test. An ignition is denoted as “+” and no ignition is denoted as “-”. 5 drops were put into the Erlenmeyer flask at each temperature.

In the preliminary test, the lowest temperature at which an ignition occurred was 306 °C.
The lowest temperatures at which an ignition occurred in the main test are given in Table2.
